Abstract

A facility for identifying a location in a printed document is described. The facility obtains an image of the printed document, and extracts gestalt information from text occurring in the image of the printed document. The facility compares the extracted gestalt information to an index of documents and, based upon this comparison, identifies a document that includes the gestalt information.
